Pultec-style tube EQ
The EAR 822
EQ Pultec type equaliser has been designed to be highly flexible and thus
useful in a wide range of applications. Passive equalisation networks combined
with valve input and output buffers are used in order to minimise disturbing
side effects such as phase shift and ringing.
The audio circuitry conforms to
the EAR principles of simplicity and subjective ÒtransparencyÓ, with low
distortion at all normal signal levels. A "clickless" bypass switch
allows easy comparison between the processed and direct paths. Variations in
response include low pass, high pass, band pass and high or low frequency shelf
with variable Q and turnover frequency.
